Kind of a noob question but do headers help that much or are they not worth the money.

Okay first of all, let me ask this. Did you search, even a little bit?

But since yout took the time to ask, I have to answer with as little lip as possible. No, they will not help at most tuner's levels, and they make your car sound less like a Subaru and more like a Honda. They make you lose a lot of low end power, and gain a tiny bit of high end power. For most tuners this is true, but with higher power cars they can get gains with them when tuned right.
